描述

1）PPI協(xié)議：西門子專為S7-200開發(fā)的通訊協(xié)議

2）MPI協(xié)議：不完全支持，只能作從站

3）自由口模式：由用戶自定義的通訊協(xié)議，用于與其他串行通訊設備通訊（如串行打印機等）。

S7-200編程軟件Micro/WIN提供了通過自由口模式實現(xiàn)的通訊功能：

1）USS指令庫：用于S7-200與西門子變頻器（MM4系列、SINAMICS G110和老的MM3系列）

2）Modbus RTU指令庫：用于與支持Modbus RTU主站協(xié)議的設備通訊

S7-200 CPU上的兩個通訊口基本一樣，沒有什么特殊的區(qū)別。它們可以各自在不同的模式、通訊速率下工作；它們的口地址甚至也可相同。分別連接到CPU上兩個通訊口上的設備，不屬于同一個網(wǎng)絡。S7-200 CPU不能充當網(wǎng)橋的作用。
